Dad-of-three Adam, who’d now be 61, disappeared from his home in Kilbarchan, Renfrewshire, 18 years later in 2001 and has never been seen since.

Even now, Margaret cannot bring herself to say his name — but she’s not convinced he is dead. She said: “It’s easy enough to disappear if you want to.”

After so many years Margaret hardly dare hope for resolution but she knows it would help her family — including Tracey’s brother, Brian, 44, and her other daughter, Kimberley McKay, 28 — to move forward.
She added: “Tracey could have had weans, I could have had my daughter and her grandkids. If we were to know for sure who killed her, it would be like an ending.”
